Title: Cyclonic mixing and combustion chamber for circulating fluidized bed boilers
Inventor: PERUSKI MARK E
IPC: F23C10/02
Filed: 1992-09-02
Abstract: ABSTRACT OF THE DISCLOSURE     An  apparatus  for  supplying  fluidized  bed material  to  a circulating fluidized bed boiler having a primary zone with a fuel feed point and a furnace zone above the primary zone,  a mixing chamber for receiving solid fuel and a portion of the total combustion air needed in the boiler.  The combustion air and             circulating  fluidized  bed  solids  are  supplied tangentially into the chamber which is advantageously in the form of a horizontally extending cylinder.   The combustion air and solids  are  intimately mixed with  each other  before  they  are discharged into the primary zone of the boiler.  The primary zone of  the  boiler  is  shaped  with  an  upwardly  increasing  cross sectional  area  so that the already mixed combustion air  and solids diffuse evenly through the fluidized bed boiler.

Title: Improved golf ball covers containing high acid ionomers
Inventor: SULLIVAN MICHAEL J
IPC: A63B37/12
Filed: 1992-09-22
Abstract: The present invention is directed to a golf ball comprising a core and a cover, wherein the cover comprises a blend of two or more high acid ionomer resins. Each high acid ionomer resin utilized in the blend of the cover composition comprises generally of greater than 16% by weight acid, preferably from about 17 to about 25% by weight acid and more preferably from about 18.5% to about 21.5% by weight acid.

Patent CA-2081165-A1 (CA)
Inventor: BALES BRUCE M
IPC: H04Q3/545
Filed: 1992-10-22
Abstract: A system for distributing a numbering plan to switching nodes which are organized in a dialing plan hierarchy and for allowing an individual switching node to redistribute blocks of numbers to other switching nodes upon requests from those switching nodes to own the requested blocks of numbers. Further, the dialing plan hierarchy is automatically established upon system initialization with eachswitching node determining its position in that hierarchy. In addition, a switching node that needs to use only one number of a block owned by another switching node can request permission from the other switching node to use that telephone number for a telephone connected to the switching node. Such a use is referred to as hosting the telephone number. Hosting allows a telephone connected to one switching nodeto have a telephone number owned by another switching node and eliminates the constraint of requiring every telephone connected to a switching node to use a number from the block of numbers own by that switching node.

Title: Neural processing devices for handling real-valued inputs
Inventor: TAYLOR JOHN G
IPC: G06F15/18
Filed: 1991-06-28
Abstract: A neuron for use in a neural processing network, comprises a memory having a plurality of storage locations (3) at each of which a number representing a probability is stored, each of the storage locations being selectively addressable to cause the contents of the location to be read to an input of a comparator (2). A noise generator (1) inputs to the comparator a random number representing noise. At an output of the comparator an output signal (4) appears having a first or second value depending on the values of the numbers received from the addressed storage location and the noise generator, the probability of the output signal having a given one of the first and second values being determined by the number at the addressed location. The address inputs for the memory are derived from a real-to-spike frequency translator (28) which has real values as its input vector (26).

IPC: B01D17/02
Filed: 1993-07-08
Abstract: Described is a novel process for regenerating an ASO contaminated alkylation catalyst which contains a sulfone component and a hydrogen halide component. The alkylation catalyst undergoes a series of separation steps to remove a significant portion of the hydrogen halide component contained therein followed by a phase separation between an ASO phase and a sulfone phase. The sulfone phase is then contacted with a carbon material to remove a portion of any remaining ASO contained in the sulfone. <IMAGE>

Title: Scale having variable thickness document feed belt with feed transport control
Inventor: RYDZAK STANLEY
IPC: G01G19/00
Filed: 1993-07-30
Abstract: A transport apparatus for a weighing module includes a scale which has a deck connected to a scale base for weighing an object placed on the deck. The deck has slots for accommodating dual thickness belts which are arranged below the deck to be in substantial registration with the slots. The belts are positioned with respect to the slot such that in a home position a thinner section of the belt does not protrude through the slot whereby the transport means does not interfere with weighing of the object on the deck. When the belts are actuated, the dual thickness belts move so that a thicker section of each belt protrudes through the slot as the belts are being driven to thereby lift the object from the deck onto the thicker section of the belt to transport the object on the belt. In order to provide a safety factor in the event that something is caught in the belts in order to detect problems in the operation of the belts, the belts are monitored using a photodetector for measuring the actual travel time of the belt and comparing it to an expected time. The detector makes use of the slots in the belt to check the transitions between slot and tooth.

Title: Easy open package, film and method of construction
Inventor: SCHLAEPPI BLAKE

Patent CA-2103410-A1 (CA)
Title: Ink-cooled thermal ink jet printhead
Inventor: SECCOMBE DANA
IPC: B41J2/36
Filed: 1993-11-18
Abstract: An ink-cooled inkjet print cartridge (20) has an efficient heat exchanger (22) located on the back side of the substrate (30) that eliminates the need for heat sinks. All ink (38) flowing to the firing chambers (40) goes through the heat exchanger (22). The geometry of the heat exchanger (22) is chosen so that almost all the residual heat absorbed by the printhead substrate (30) is transferred to the ink (38) as it flows to the firing chambers (40). Additionally, the pressure drop of the ink flowing through the heat exchanger (22) is low enough so that it does not significantly reduce the refill rate of the firing chambers (40). The heat exchanger (22) can have one or more active heat exchanger sides. The heat exchanger has little thermal mass itself and significantly reduces the thermal mass of printhead by eliminating the need for a heat sink. This reduces the warm-up time of the printhead to a fraction of a second.
